This invention relates to devices for producing proofs from the cast lines from type-bar casting machines of the kind, whereina paper supported by a yielding platen is arranged directly outside the channel, (delivering channel),

from which the cast lines are pushed out according as they are cast, and receives the impression directly or through ink ribbon during the motion of the line between the delivering channel and the galley.

Hitherto, the paper-Was supported ina swinging frame which maintains normally the platen in a withdrawn position but, as soon as the cast line has come nearly quite out-from the channel, is put in a rapid motion firstly against the line to receive the proof on the paper and immediately thereafter from the line back into normal resting position, whereupon the line is moved sidewise on to the galley. 'During this rapid motion it is diflicult to obtain a perfect proof. Besides, the good result depends upon a very exact constructional execution and co-operation of the members controlling the line-delivering and controlling" the swinging-motion of the frame, and inaddition a new adjustment of the parts is necessary upon a small wear of the parts or as soon as a very small lost-motion has arisen.

The present invention is characterized substantially by such an arrangement of the platen just outside the delivering-channel and at so short a distance from its mouth that the platen is struck by the line during the first part of its travel out from the channel and is pushed completely or partly back by the line proper during the impression of the proof, the platen being then held stationary in a withdrawn position allowing the succeeding sidewise motion of the line on to the galley.

In this manner the proof-producing pressure will last a great part of the motion of the line out from the channel, whereby a perfect proof is obtained.

Further, the frame, instead of performing a swinging motion, is movable in rectilinear guides parallel to 'the delivering-channel and is adapted to be carried forward again into a new proof-receiving position, before the next line is pushed out.

The invention is illustrated in two embodiments in Figs. 1 and 2 of the annexed drawings showing plan views partly in section of the proof-printing device proper.

In the construction shown in Fig. l, 1 denotes a portion of a type-bar casting machine where type slugs are ejected and the composed letters are cast line after line in ordinary manner. The finished cast lines 2 arrive one after. the other through the delivering-channel 3 by means of the mechanisms which are presumed to be well-known and which form no part of the present invention. Then the delivered lines one after the other are conveyed to one side (to the left in the drawings)" on to the galley 4 to be collected therein and to be transierred later on for further treatment. A paper ribbon 6 and an ink ribbon 7 travel in well-known manner past theyielding platen 5. The line consequently produces a proof on the ribbon, and the parts move back into a position, whereinthey are locked provisionally, whereupon the line is passed on to the galley. 8 denotes the'movable frame carrying the platen, the paper and the ink ribbon.

parallel side edges 9, 10 moving in stationary guides 11 and 12 respectively attached to the side of the machine 1 by means of a plate or a bracket 13. These guides are arranged parallel to the delivering-channel 3. 30 The paper ribbon 6 is supplied from a bobbin 15 carried at 14 on the frame and is passed forwards over a guide-roller 16, further over the platen 5 and back and out between feeding 'rollers 17, 18, whereof one '17 is mounted on the '55 same shaft 23 as a ratchet wheel 19, whose pawl is pivoted on a fixed pin 21 on the bracket 13 and is pressed against the ratchet wheel by a spring 22.

The ink ribbon 7 is moved between two bobbins 24 and 25 by a mechanism similar to that used in typewriters, so that the ribbon travels one step upon each impression made against the platen 5.

One ledge 9 of the frame 8 has a pin 26 which is caught by a hook 28pivoted at 27 on the bracket 13 under the influence of a spring,v 29. The other guide ledge 10 of the frame has a bar 30 which slides in a fixed guide-bolt 31 and is provided outside same with regulating nuts'32, 109

this position may be easily so adjusted by the nut that the platen stops in its inner position (normal resting position) at a short distance outside the mouth of channel 3 as shown in Fig. 110

1. The tail 36 of hook 28 is under control of a lever 37 mounted on one end of a turnable rod 40 which is journalled at 38 and 39 on the bracket 13 or the guide 11 and whose other end is provided with a side arm 41 under influence of a nose 43 arranged on one of the periodically moved-members of the machine 1, for instance the elevator 43;

The operation is as follows:

The parts are in the position shown in the drawings, and a line 2 just east is pushed out from channel 3.

During this motion the line. strikes against the ink ribbon 7 and presses same against paper ribbon 6 and the latter against platen 5 which now yields back together with the whole frame 8 and the parts mounted thereon, the springs 34, 35 being further extended and the frame sliding in its guides, until hook 28 snaps over pin 26 and locks the frame in withdrawn position. During ,this backward motion the types of line 2 press against the paper. and impart to same a good proof. After the locking of the frame, the line -2 freed of the piaten 5 is conducted on to v galley 4 as usually. Immediately thereafter the projection 42 on elevat or 43 strikes lever 41, thereby iturning bar 40, whereby arm 37 swings tail 36 to the left to release hook 28. Nowthe springs 35 again-pull the framewith its parts forwards into the resting position shown, pawl 20 thereby rotating ratehet wheel 19 and feed roller 17 one step, wherebypaper 6 is advanced one line'distance. Inkribbon 7 is simultaneously advanced, and the parts are ready forreceiving a new impression.

' Inthe modificationshowninFig. 2 the bracket 13 carries twof arms 45 turnable about pins .46. said; arms carries twoadjustable projections 47 permitting the side pin 46 of frame8 to pass easily in; direction towards channel 3 but opposingthemovementin oppositedirection with a definite-force (proof pressure). Thisforce depends upon the friction between 48 and 47 and may be varied by theadjustabiespring 49 connecting the outer ends of. arms 45 and tending to draw them together into contactwith the adjustable I screws 50.

Up on line 2 underresistancehas forced pin 48 past the projections 47, frame 8-with proof ribbon 6 is movedfurther back. by-a special driving device.

' A vertically reciprocating .member 43 (elevator) of. the machine carries a. cam guide 44 located partly vertically and partly inclined laterally. The inclined portion-ofssaid guide acts on the inner end .of a lever 51 to move it..horizontally. Theouterendof lever 51. which turns about a fixed pin 53 is pivotally connected with the short arm of a bell crank lever 54, whose long arm is attached to frame} by.a bolt.55. V

In order to adjust, the line .distaneeon paper ribbon fi the. pawl 20 is pivotally attached toa lever 56, .whose fixed. fulcrum on bracket 13 may be altered for instance from .57. to 58, whereby the pawl is caused togrip over two or more teeth of ratchetwheel l e atatime. In the. connection between pin 55 and guide 44through the parts 54,51 and 52 there should be so much lost motion that pin48 can be forced past the. projections 47 before roller 52, engages the left hand side of cam guide. 44, or the guide maybe so shaped thatthe same through the said parts provisionally does not exert any pull on frame awhi ch will thereforeactas if it [were quite free as long as the projections 47 have to exert their a higher velocitythan that, with which the line "2 is pushed further outwards.

When therefore the line has got quite out from the channel, the platen 5 has been pulled quite free of the line. Consequently the latter may be pushed aside on to the galley 4. During these motions the cam guide 44 stops its movement and commences to travel vertically in the opposite direction, thereby pressing frame 8 with platen 5 etc. back into the resting position shown so as to be ready to receive the next proof. During such-return'movement the pin 48 travels easily past the pivoted projections 47 'A still safer operation is obtained by the addij;

tional meinbers 59-62 indicated in Fig. 2. One of the bars 10 has an extension 59 with an adjusting screw 60. A rod 61 is in connection with the mechanism pushing out the line 2. Immediately the line 2 has effected the proof, the rod 61 strik s the adjusting screw and assists in pressing back the frame in order to remove the resistance at 48, whereupon a spring-62 pulls the frame 8 and carried parts rapidly back, the small lost motion between-52 and 44 being annulled. 1

The hot line, not always of full length, will contact the paperonly for a very short period, but long enough to yield a perfect proof.
